Hi Everyone. Have just joined & this is my first post! Need a bit of advice. My windscreen wipers packed up yesterday in the heavy rain and now the motor whines when I turn them on but nothing moves. Do I need a new motor and would one from a 1.7L P reg turbo diesel or a 1.6L L Reg fit? I have a Mk 3 1994 M Reg 1.8L petrol Astra. Many Thanks.
